Chapter 17: Q17-5TYU (page 362)

Which component is not directly involved in translation?

  1. GTP

  2. DNA

  3. tRNA

  4. ribosomes

Short Answer

Expert verified

  1. The option 鈥淕TP鈥� isfalse.

  2. The option 鈥淒NA鈥� istrue.

  3. The option 鈥渢RNA鈥� is false.

  4. The option 鈥渞ibosomes鈥� is false.

Step by step solution

01

Translation

The translation process mediates the synthesis of proteins from mRNA molecules with the help of tRNA and ribosomes. GTP (guanosine triphosphate) is used as a source of energy during translation.

02

Explanation of option (A)

GTP is hydrolyzed during translation. This provides energy that facilitates the binding of tRNA to the ribosomes. It also helps in the movement of ribosomes along the mRNA molecule.

Thus, GTP is involved in translation.

Therefore, the given option is false.

03

Explanation of option (B)

The transcription process mediates the synthesis of mRNA molecules using one of the DNA strands as a template. DNA has no role in translation.

Thus, DNA is not involved in translation.

Therefore, the given option is true.

04

Explanation of option (C)

tRNA recognizes mRNA codon and brings the appropriate amino acid to the mRNA molecules. It binds to the mRNA and delivers the amino acid to the polypeptide chain.

Thus, tRNA is involved in translation.

Therefore, the given option is false.

05

Explanation of option (D)

The ribosome binds to the mRNA molecules and joins the amino acids delivered by the tRNA to form the polypeptide chain.

Thus, ribosomes are involved in translation.

Therefore, the given option is false.

Would the coupling of the processes shown in Figure 17.24 be found in a eukaryotic cell? Explain why or why not.

In eukaryotic cells, mRNAs have been found to have a circular arrangement in which proteins hold the poly-A tail near the 5鈥� cap. How might this increase translation efficiency?

The anticodon of a particular tRNA molecule is:

  1. complementary to the corresponding mRNA codon.

  2. complementary to the corresponding triplet in rRNA.

  3. the part of tRNA that bonds to a specific amino acid.

  4. catalytic, making the tRNA a ribozyme.

(a) Based on the logo, what five adjacent base positions in the 5' UTR region are most likely involved in ribosome binding? Explain. (b) What is represented by the bases in positions 0-2?

What would be the effect of treating cells with an agent that removed the cap from mRNAs?
